SPECIFICATION forming part of Letters Eatent No. 672,348, dated April 16, 1901.

Application filed December 14, 1898. Serial No. 699,282. (No model.) i

To all whom it may concern:

Be it known that 1, JAMES A. BONSAOK, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Cigarette- Machines, of which the following is a specification, reference being had to the accom panying drawings and to the letters and numerals of reference marked thereon.

My invention relates to mechanism for antomatically manufacturing cigarettes of the variety known as Russian mouthpiece-cigarettes, in which a reeled web of paper for forming the wrappers is carried through suitable devices, whereby it is folded and its edges are united to form a continuous tube, which is subsequently cut into proper lengths by means provided for that purpose. Each tubular wrapper thus formed is carried in line with the mouthpiece-forming mechanism, which having separated a length of stout paper from a continuous web and rolled it into a tubular form introduces it into one end of the tubular wrapper. While these movements are progressing, tobacco from a suitable receptacle isfed onto a movable receiving-surface divided by partitions into equal spaces, so that a uniform quantity of tobacco will be received in each subdivision, the said quantities of tobacco being fed successively to a compressing mechanism, whereby each portion is condensed sufficiently to be introduced into a mold formed on a rotating disk, which mold shapes the condensed tobacco into a filler of the proper size and form and holds it under compression for a certain time to give it a temporary set. The filler is then removed from the mold and pushed endwise into the cigarette-tube placed in position to receive it. The cigarette is then dropped onto a delivering mechanism, which carries it to a rolling device, which perfects its shape before ejection from the machine.

In connection with the wrapper-feed mechanism I have arranged an apparatus for printing or printing and bronzing letters and characters on the web before it passes through the feed-rolls, the printing being so spaced as to appear in the same position on each finished cigarette.

To more clearly understand the invention,

attention is called to the drawings accompanying this description, in which- Figure 1 is a plan view of a cigarette-machine embodying my invention. Fig. 2 is a cross-section of the same on the line 2 2 of Fig. 1. Fig. 3 is a similar section on the line 3 3 of the same figure. Fig. 4 is a horizontal section on the line 4 4 of Fig. 2.

Fig. 46 is a front elevation of the printing apparatus with the front removed, showing the interior arrangement. Fig. 47 is a rear elevation of the same.

Similar letters and numerals of reference indicate the same parts in the various figures.

On a bed-plate 1, supported by legs 2, are secured the various mechanisms for forming the tubular wrapper, mouthpiece, and filler and assembling these several parts successively into a complete cigarette and finally delivering it into a suitable receptacle. At the right-hand end of the bed-plate 1 and bolted thereto is a bracket A, Figs. 1 and 46, and journaled in bearings thereon are two feed-rolls A A for drawing the web a of wrapper material from a reel. The lower roll A which is of greater diameter than the upper one, A, has a groove 0. in its center to permit the belt A to pass without coming in contact with or being engaged by the rolls. The web a, which is slightly wider than the belt A is thus grasped only at its edges between the rolls A A a handscrew a being employed to separate the rolls. Fixed to a bar a attached to the bracket A, is a trough-shaped guide A through which the wrapper passes to the tube-forming device and by which it is bent into U form. Idle rollers a a are pivoted in the bracket A, around which the belt A passes, while an idle roller a is journaled in an adjusting device on a bracket A fixed to the bed-plate, for maintaining the tension of the belt. The belt A after running around the idle rollers a a a", as shown, passes horizontally beneath the trough-shaped guide A and in line therewith through the tube-forming device to and around a pulley B on a horizontally-disposed transverse shaft B, turning in hearings on the bed-plate 1. After passing around the pulley B the belt A returns over an idler b to the starting-point.

'Attached to the upper surface of the bedplate 1, as indicated in Fig. 1, between the bracket A and the pulley B, is a horizontal (Not shown.)'

porting-plate e, fastened to the plate E plate 0, to which is bolted a second plate D, having an arm 61 projecting toward the pulley B. Gear-wheels D D engaging each other, turn on studs attached to one side of the arm (1, the gear-wheel D being driven by wheel B mounted on the transverse shaft B. In the construction illustrated the wheel B is formed as an extension of the pulley B. A block D screwed to the second plate D, gives support to a short cross-shaft d, on which a forked bracket D is adapted to rock. This forked bracket D carries a shaft (1 lying parallel to the cross-shaft 61, said shaft 01 having on one end a pinion meshing with the wheel D and on the other end a serrated disk or cri m ping-wheel 3. Beneath or in a lower plane than the crimpingwheel 3 is the tube forming device (indicated as an entirety by E) which shapes the wrapper into tubular form, folds the contiguous edges, and in c0115 nection with the crimping-wheel firmly unites the folded edges. The crimping-wheel 3 is held against the fold or seam of the wrappertube by means of a spring d ,connected to a finger d projecting from the forked bracket D and to an arm on the plate 0.

The web a passes from the trough-shaped guide A into a channel E, Figs. 1, 7, 9, 10, 11, and 12, in the tube-forming device E. Within the channel and supported by the block D is a mandrel E having a diameter substantially equal to that of the cigarettefiller, around which mandrel the continuous tube is formed. The channel E passes lougitudinally through a fixed block E and a removable block E the latter block giving support to two plates E E held in place thereon by pins, which arrangement admits of the easy removal of the plates when necessary. Screwed to the plate E is the edgefolder E Figs. 6, 8, 12, 13, 14, 14*, and 14 which consists of a part e, pivoted to a sup- Diagonally downward through the forward end of and across the part 6 is bored a preferably cylindrical hole 6 from which a narrow tangential slot 6 extends to the under surface of said part 6, preferably at an angle of sixty degrees thereto. direction of the cylindrical hole is substan tially as shown in Figs. 14 and 14". By this construction the edges of the wrapper which project above the plates E E", as seen in Fig. 11, enter the tangential slot 6 of the part e on the side shown in Fig. 13 and emerge on the opposite side, Fig. 14. The cylindrical hole 2 by reason of its position and direction, turns or folds the edges of the wrapper in the manner represented at 15, Fig. 15. The mandrel E is cut away at a point immediately in front of the part e and a small corrugated wheel a pivoted therein, the upper surface of its periphery being slightly above the upper surface of the mandrel. The corrugated crimping-wheel 3,which is directly above said corrugated wheel 6 Fig. 8, coacts with it and presses or crimps the fold into the form The diagonal IIO shown at 15 Fig. 15, as soon as it emerges from thefolder. The edge-folder E is screwed to the plate E in such position that the axis of the cylindrical hole 6 is substantially in the same vertical plane as the axis of the wrapper-tube, Figs. 13, 14, 14*, and 14t the purpose being to make the seam of the tube parallel with its sides or axis. A finger e overhangs the part 6, between which a light spring 6 is placed to keep the said part down to its work.

The continuous wrapper-tube, constructed as above described, is drawn through the tube-forming mechanism E by the bite of the crimping-wheels 3 e on the seam of the tube. The peripheral speed of the crimping-Wheels is but little faster than the peripheral speed of the feed-rolls A A the result being that the web a is always kept taut, the crimpingwheels slipping when the strain on the web reaches a given tension. In this connection it is to be noted that the web a is fed to the feed-rolls A A over the roller a in order that it may pass partly around the roll A and be straightened before it is gripped by the roll A Experience has shown that when the web, as in the present case, is held by its edges only between the rolls, if it is fed in a straight line it will not pass evenly through the rolls, but will wrinkle and run off,which difficulty I have overcome in the manner described. After passing the crimping-wheels the continuous wrapper-tube moves onward in a straight line, passing into a rotary carrier G, and a sufficient length of the wrapper-tube to form a cigarette having entered said carrier a cutting mechanism F severs such length from the continuous tube.

The tube-cutting mechanism comprises a plate F, Figs. 1, 2, 5, and 34, adapted to slide in guidesfon the bed-plate 1, the movement of an eccentric F on a vertical shaft t operating a rod f connected to the sliding plate F, Figs. 1, 2, and 3st. Extending upwardly from the plate F and at an angle thereto is an arm f having an attached cutting-blade f. In bearings on the plate F and adapted to rock therein is a shaft F to which is pivoted a blade f adapted to coact with the stationary bladef A finger F also attached to the roclcshaftf is held against a cam F on a shaft 6 by a spring f, the rotation of the shaft 6 causing the cam F to actuate the blade f andseverthe wrapper-tube. The vibratory blade f is held against the stationary blade by means of a spring f which draws against the former, as shown more part icularlyin Fig. l. The reciprocating action of the knifeis so timed that when it is moving in unison with or a little faster than the continuous wrappertube a length sufficient to form a cigarette has passed between the blades of the cutter, which are then quickly closed, severing a section and pushing it to place in the rotary carrier G. The tube being empty the knife flattens it before cutting off a section. This be ing so the necessity of perfect harmony of movement between the tube and knife is not required, and better results are obtained when the knife moves a little faster than the tube, as danger of crushing the end of the tube by butting against the knife is avoided.

The rotary carrier G, Figs 1, 2, and 5, consists of a flanged disk G and a fiat disk G spaced a suitable distance apart and connected at their centers by a hub g, through. which passes a shaft G fixed therein by means of a pin, the said shaft being journaled in a bearing g on the bed-plate 1. The periphery of each disk G G is provided with notches 9 as shown, slightly larger than the diameter of a cigarette and semicircular on the bottom. These notches form supports for the cirgarette-tubes after being separated from the continuous wrapper-tube. The rotary carrier G is advanced step by step by means of a ratchet-wheel G having as many teeth as there are notches in the carrier, fixed on the shaft G A pin g on a reciprocating bar g engages with and operates the ratchetwheel G the reciprocating bar being driven by a cam G on the shaft 5 beneath the bedplate 1, Figs. 3 and 4:. A spring g retains the pin g in engagement with the ratchetwheel G Secured to a fixed portion of the machine above the rotary carrier G and in line with the wrapper-tube is a guide H, Figs. 1 and 4:45, which serves to keep the severed portion. of the Wrapper-tubein position, so thatitcannot fail to enter a notch g of each disk of the rotary carrier. To insure the entrance of the cigarette-tube into a notch g a lever H is pivoted loosely on the shaft F of the cutting mechanism, one end of which extends upwardly and terminates in a footpiece h, adapted to pass thrpugh a slot 77. in the top of the guide H. The other end of the lever H is moved by a cam 72 secured to the shaft 6. A spring 72. attached to the lever H and to some fixed point, serves to withdraw the footpiece from the guide H after the cam 72 ceases to act. A curved finger h, having the same radius as that of the disk G lies close to the inner side of said disk and extends from the guide H, to which it is attached, a short distance in the direction of rotation of the rotary carrier G, said finger serving to prevent the accidental displacement of the cigarette-tubes which pass under it. in the rotary carrier. The rotary carrier G, advancing intermittently as the cigarette-tubes are placed within the peripheral notches 9 brings each onein turnin position for the insertion of a mouthpiece, the mechanism for cutting, winding, and placing which within a cigarette-tube will now be described.

Bolted to the bed-plate 1 at the front and near the left-hand end is a standard 1, Figs. 1, 2, and 3, having bearings for feed rolls 1 1 placed one above the other. A curved guide I placed in front of the said rolls, leads the web 71 of mouthpiece materialusnally a heavier paper than that of the cigarette-tube TIO rotate the pin to the right.

from a reel (not shown) placed conveniently to the feed-rolls. Behind the feed-rolls I I is a table J, over which the mouthpiece-paper travels to the winding device, the table J being supported'on a standard J in a horizontal position above the bed-plate 1. On the top of the table J are fastened two steel plates or cutting-blades J J Figs. 16 and 18, the former having an edge 7' at an angle of about forty-five degrees to the direction of travel of the paper, while the cutting edge j of the latter plateis at a right angle thereto. A stud j is fixed to and projects from the bottom of the table J, a gear-wheel J being mounted on the stud and adapted to rotate thereon. The gear-wheel J engages a second gear-wheel J adapted to turn loosely on a pinj passing through and extending below the table J, and having fixed to it a ratchet-wheel J which connects with the gear-wheel J 5 by means of the pawlj, Fig. 17. A rack-bar J held in connection with the gear-wheel J by means of an antifriction-rollerj, is secured to and operated by one arm of a three-armed lever K, hereinafter described, pivoted to the bedplate. The movement of the rack-bar to the right causes the gear-wheels J J 5 to rotate, and the pawl engaging the ratchet-wheel will The upper end of the pin j, which is flattened and roughened, passes through the plate J just back of the cutting edge j Figs. 18 and 34, and projects very slightly above its upper surface.

Pivoted loosely on the shaft I of the lower feed-r0111 and to the left thereof is a curved arm L, Figs. 1 and 18, from which a lug lextends toward the table J. To the under side of this lug is secured a cover-plate L, which extends above that portion of the plate J over which the web t' passes. A socket Z is formed on the cover-plate L, in which socket is seated a button L, the lower surface of which extends a slight distance below the bottom of the cover-plate. The button L is situated, when the parts are in normal position, axially above the pin 7' The button is held in place bya pivot-pin L fixed against movement by a screw Z To permit the button to rotate with the least possible friction, the lower end of the pivot-pin L is made pointed and is seated in a conical depression in the button L having an angle wider than the pivotpoint, so that only the extreme point of the pin will bear on the button.

When the feed-rolls rotate to advance the paper, the curved arm L is elevated by a cam means for performing these operations are further described hereinafter.

A bracket M, Figs. 1, 2, and 3, bolted to the front edge of the bed-plate, extends upwardly therefrom for a short distance, and to the bracket is pivoted a knife-carrying lever M, which curves rearwardly over the table J. To the free end m of said lever are pivoted two flat knives M M gwhich reach downwardly and coact with the edges j f' of the plates or cutting-blades J J the angular position of the knives corresponding to that of the cutting edges j The upper end of each knife is secured to a hinge-plate m, pivoted to a fiat hinge-plate m one of the latter being fastened to the upper and one to the lower side of the knife-carrying lever M. A spring m between the plates m m of each hinge tends at all times to keep the cutting edges of the knives in contact with the respective cutting edgesj j On an arm M which projects laterally from the knife-carrying arm M, is a roller m operated by a cam M fixed on the shaft 7.

Each rotation of the feed-rolls I I a'cl vaneing paper sufficient for two mouthpieces in less time than is required to make one cigarette, means are employed to stop the feedrolls for a definite period. Such means are shown in Figs. 1, 41, and 42 and consist of a gear-wheel 8 on the shaft 6, meshing with a slightly-larger gear-wheel 9, adapted to turn loosely on a stud 10, fixed in a bracket 1', ex-

tending upwardly from one of the bearings i of the shaft 6. A gear-wheel 11 is attached to the gear-wheel 9 on the outside, while a disk 12, fastened to the inside thereof, is formed with notches 12 12, one being on each side of a fork-like projection 12. A gearwheel 13 on the shaft of the lower feed-roll I is turned by the gear 11, and through the equal gears 14: 15 motion is imparted to the upper feed-roll I On the shaft 6, below the disk 12, is mounted a collar 16, having a peripheral opening 17 therein and also a hub on which is secured an arm 18, provided with a roller 19, projecting over the collar 16. The parts being in the position shown in Fig. 41, the shaft 6 will make the greater part of a revolution without turning the gear 9, as the teeth are omitted from the portion 9 thereof. As the arm 18 reaches the position indicated by dotted lines the roller 19 engages the notch 12 of the disk 12 and rotates it until the teeth of the gears 8 and 9 become engaged, thus causing the feed-rolls I I to make one revolution and feed a length of paper equal to two mouthpiece-blanks, at which time the roller 19 will engage the notch 12 and move the disk 12 to the position shown, the toothless portion 9 of the gear 9 being next the gear 8. The roller 19 will pass out from the notch 12 and the shaft 6 continue its rotation without turning the gear 9, which is held in position by the fork-like projection 12, riding on the collar 16, into the opening 17 of which a prong of the said foot-like extension enters when the roller is engaged with a notch. The curved arm L and the knife-carrying lever M are
